GNSS-stations velocity database on the East European Craton for research and practical applications

Abstract

This paper contains the description and principles underlying the development of the velocities database of almost 500 GNSS stations with an observational duration of more than two years. They are mainly located in the territory of Eastern and Northern Europe. Various station-motion models, a multi-step technique for filtering the outliers, estimation of errors for station velocities considering different types of noise distribution as well as accounting discontinues in position time-series of stations are used when creating this base. More than 60 % of the stations are owned and constantly updated with data from various geodetic institutions of the Russian Federation. All the data is presented for the first time within one homogeneously processed database. Velocity field of the stations was used for studying the motion of the East European Craton and its parts, Baltic Shield and Russian Plate. An example of atmospheric parametres monitoring for a particularly dense network of this base around the Gulf of Finland is also given.
